Visibility of Temporary Queues outide of its MOM

Hi,
For my assignment I need to have an request reponse JMS model and I do not want to use message selector to pick the right response message,as i consider it would not perforem better when the load is more. My system sends a message to an extenal MOM, which send it is reply back to the temporary Queue(getReplyTo()) created in my application. My question is can an exteranl system access/send message to the temporary Queue created by an other MOM.

I also thought of using a temporary queue for my assignment, to model a request-response type of communication. But since it's going to be quite chatty I think the performance will be gravelly affected due to to creation of all these temporary queues. I decided to use a permanent queue with correlated ids and go for the message selector.
